Abstract (en)
[origin: EP1764476A2] A rotor assembly or "blisk" for a gas turbine engine includes a metallic hub (12) having an annular flow-path surface (14), and at least one blade (16) extending outwardly from the flow-path surface (14). The blade includes a metallic body (18) having a first density. The metallic body (18) defines a shank portion (22) and an airfoil portion (20) having opposed pressure and suction sides, and is integral with the hub (12). An insert (36) having a second density less than the first density is carried by the body (18), and the insert (36) and the body (18) collectively define an airfoil shape. A method is also provided for manufacturing a rotor assembly.
